我不知道我现在的问题是什么，但这里发生了什么，我对雄辩的
列表方法有问题
以下一行：
dd(Quiz::lists('name', 'id')->all());

返回此错误：
ErrorException: explode() expects parameter 2 to be string, array given

堆栈跟踪似乎并没有给我太多的工作：

我已经用多个不同的模型测试了这个问题，问题仍然存在。这可能与环境有关吗？使用PHPUnit运行测试时会发生此错误，我还没有在非测试环境中尝试过。将更新后，我有
一些信息：
Laravel版本：5.1.11
服务器：宅地默认值
编辑#1
在一些测试之后，我发现问题只发生在PHPUnit测试中，测试环境中。当通过常规请求调用该方法时，不会出现此问题。
问题已解决。似乎线索在我的laravel.log
的下面一行中：
#1 /home/vagrant/.composer/vendor/illuminate/support/helpers.php(404): explode('.', Array)

我想，因为我的宅地盒子是在不久前安装的，所以该目录中的依赖项从未更新过，所以在/home/vagrant/.composer
中快速更新了编写器
